2A+Domain+and+Range

1. What was the assignment? (If it was a textbook problem, number it, then copy it or rewrite it using your own words.) =__**EF – 57: by Kimberly Bush**__=

Find the range and the domain for the following functions: a) Note: The domain of a function is the possible values for the x variable. Note: The range of a function is the possible values for the y variable.

a. In Figure A the x values are -2, -1, and 2 i. Therefore, the domain is {-2, -1, 2} b. In Figure A the y values are 0, 1, and -1 i. Therefore, the range is {0, 1, -1}

b) Note: Open circles mean that that number is not apart of the function.

a. In Figure B the x values are -1 to 1 i. Therefore, the domain is -1 < x < 1 b. In Figure B the y values are -1 to 2 i. Therefore, the range is -1 < y < 2

c) Note: Closed circles mean that that number is apart of the function.

a. In Figure C the x values are -2 to 2 i. Therefore, the domain is -2 < x < 2 b. In Figure C the y values are 1 to -2 i. Therefore, the range is -2 < y < 1

d) a. In Figure D the x values are -2 to 2 i. Therefore, the domain is -2 < x < 2 b. In Figure D the y values are -2 to 2 i. Therefore, the range is -2 < y < 2

The **Domain** of a function is the set of possible values for the independent variable. (x-values) The **Range** of a function is the set of possible values for the dependent variable. (y-values)

• - the number is apart of the function º - the number is not apart of the function

__**Solutions**__

a) In function A, the x-values are -2 to 2. The domain is -2<x<2. In function A, the y-values are -3 to 2. The range is -3<y<2.

b) In function B, the x-values are -2 to -1. The domain is -2<x<-1. In function B, the y-values are -2 to 1. The range is -2<y<1.

c) In function C, the x-values are -2 to 2. The domain -2<x<2. In function C, the y-values are 2 to 1. The range is 2<y<1.

John Derry Fx-45 In this problem you have to find the domain and range of the function 2^x.
